Good luck, hope he gets a nice tune in it!
It’s been bored out to 823cc, I wasn’t really sure what to expect as I couldn’t really find any solid figures for a set up like mine. I have a friend who bored his DOHC out to 836 who got 87 hp.11HP over stock is pretty good.
Hey Jimbonaut where did you find the 35 ft lbs torque setting for the head bolts ? I've just noticed a little oil seeping out of the gasket, I know I did all of mine down to 29ft, wondering if that's not enoughThere's many a slip between dress and drawers mate but looks like you've got it licked. Nicely done.
For the bolts, I didn't use loctite on the case bolts, but did apply some molybdenum disulphide high pressure grease to the bolt threads. For your snazzy new stainless cover bolts, they'll come with simple instructions - use a little loctite or copper anti-seize on the bolt threads and you're golden and don't torque them to the same spec you would the OEM cover bolts, but a little less.
By the way, your head bolts can be torqued higher than stated in the manual. Manual states 29ft lbs (I think) but - as yours is the F model - you can torque those bad boys down to 35ft lbs. Your studs look like this, right? -
(If so yeah, you can torque those head bolts down to 35ft lbs).
I'm a member of another forum - cb1100f.net (it's an absolute goldmine) - and one of the members there told me. The cylinder studs on the DOHC F models are different from the other 750's, allowing them to be torqued to a higher spec. 35ft lbs, no problem.Hey Jimbonaut where did you find the 35 ft lbs torque setting for the head bolts ?
